About LuminaStudio

LuminaStudio is a set of free video tools that run entirely in your browser: convert, compress, trim, extract audio, make a GIF or hide a logo. Your files stay on your device from start to finish, with no sign-up and no watermark added by the site.

Why this site exists

Most online converters ask you to upload your video to a server, wait for it to be processed and then download it again. That is slow on an average connection, and many people are reluctant to hand a family video, a work meeting or a confidential recording to an unknown service.

LuminaStudio starts from a simple idea: modern browsers are powerful enough to do the work themselves. The site provides the tool, your computer or phone does the processing, and the video never travels across the internet.

How it works

Processing relies on FFmpeg, the reference open source video software, compiled for the web (FFmpeg.wasm). It is downloaded once on your first export and then cached by your browser. If FFmpeg cannot start or the file is larger than about 1.6 GB, a second engine takes over using the video features built into the browser.

The site can produce MP4, WebM, MKV, MOV, AVI, FLV, WMV, MPEG, TS, OGV and 3GP, as well as GIF, MP3 and WAV. It also lets you cut a clip, compress a file to fit a size limit, rotate the picture, add a logo or blur part of the frame.

What LuminaStudio does not do

The site does not download videos from YouTube or other platforms and does not remove copy protection. It keeps no copy of your files: if you close the tab before saving the result, you will need to start again.

Because everything happens on your device, speed depends on its power and memory. A recent computer handles a short clip in seconds; an older phone or a file several hours long needs more patience.

Free tools and advertising

The tools are free and will stay that way. To cover costs, the site may show ads, only after you agree in the cookie banner. The details are in the privacy policy.
